[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-237118 Summary of the Invention [Problem to be solved by the invention]

[0004] When a drawer with a container placed on it is put away, an impact is applied to the drawer, causing the weight of the container to be placed on the rear frame, which may deform or damage the rear frame or the connection between the rear frame and the door frame.

[0005] One of the objects of the present disclosure is to suppress deformation of a support that supports a drawer container. [Means for solving the problem]

[0006] In one aspect of the present disclosure, a storage cabinet includes a main body having a storage chamber that opens in one direction, and a drawer housed in the storage chamber and that can be pulled out in one direction. The drawer includes a door that closes the opening, a frame that extends from the door in the one direction toward the rear of the storage chamber, a container supported by the frame, and a rod-shaped member that is fixed to the frame and located at the rear of the container. The rod-shaped member has a central portion that abuts the container, and a portion that extends diagonally upward from the central portion toward the rear, and end portions that are fixed to the frame by multiple fixing portions spaced along the longitudinal direction.

[0007] In another aspect of the present disclosure, a drawer is stored in a storage chamber of a storage cabinet having a main body with a storage chamber opening in one direction, and is capable of being pulled out in one direction. The drawer includes a door that closes the opening, a frame that extends from the door in the one direction toward the rear of the storage chamber, a container supported by the frame, and a rod-shaped member that is fixed to the frame and abuts the rear side of the container. The rod-shaped member has a central portion that abuts the container, and a portion that extends diagonally upward from the central portion toward the rear side and has an end portion that is fixed to the frame by a plurality of fixing portions spaced along the longitudinal direction.

[0008] In yet another aspect of the present disclosure, a method for manufacturing a drawer is a method for manufacturing the drawer described above. In the method for manufacturing a drawer, a plurality of fixing portions are formed by crimping a frame and an end portion at a plurality of locations in a same process. [Effects of the Invention]

[0009] According to one aspect of the present disclosure, deformation of the support body that supports the drawer container can be suppressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, a storage cabinet according to an embodiment of the present disclosure will be described in detail with reference to the drawings. In the following description, components having substantially the same functions will be referred to by the same reference numerals, and the description thereof will be incorporated herein by reference.

[0012] In this embodiment, a storage cabinet according to one embodiment of the present disclosure will be described using the refrigerator 1 shown in FIG. 1 as an example. In the following description, the side where a storage chamber provided in the storage cabinet opens is referred to as the front side, and the opposite side is referred to as the rear side. For example, in FIG. 3, the lower side of the page is the front side, and the upper side of the page is the rear side. The up-down direction of the page in FIG. 3 is referred to as the front-to-back direction (depth direction). The left-to-right direction of the page in FIG. 3 is referred to as the width direction. The direction perpendicular to both the front-to-back direction and the width direction (for example, the up-to-down direction of the page in FIG. 4) is referred to as the height direction.

[0013] It should be noted that a storage cabinet is a general term for a device that has a storage chamber for storing items and allows items to be put in and taken out of the storage chamber. The storage cabinet may be, for example, a cooling cabinet that has the function of cooling the storage chamber. The storage cabinet may be, for example, a heating cabinet that has the function of heating the storage chamber. The storage cabinet may have, for example, a mechanism for changing the temperature of the storage chamber as described above. However, in the present invention, the storage cabinet is not limited to this. The storage cabinet may be, for example, a storage cabinet that does not have a temperature adjustment mechanism that changes the temperature of the storage chamber. The storage cabinet may have, for example, a storage chamber whose temperature can be adjusted by a temperature adjustment mechanism and a storage chamber that is not temperature adjusted.

[0014] The items stored in the storehouse are not particularly limited. The storehouse may store, for example, foods such as vegetables, fruits, meat, fish, dairy products such as cheese, beverages, and the like.

[0015] (Refrigerator 1) In this embodiment, a refrigerator 1 having a cooling mechanism for lowering the temperature of a storage compartment will be described in detail. Here, the term "refrigerator" is a general term for refrigerators having at least one cooling compartment (storage compartment) that can be cooled. The cooling compartment may include, for example, a refrigerator compartment or a vegetable compartment that can be cooled to a temperature range higher than 0°C (for example, a set temperature of about 5°C). The cooling compartment may include, for example, a chilled compartment or a partial compartment that can be cooled to a temperature around 0°C. The cooling compartment may include, for example, a freezer compartment that can be cooled to a temperature range below 0°C (for example, a set temperature of -15°C to -40°C, typically about -18°C to -23°C). It is sufficient for the refrigerator to have at least one cooling compartment selected from the group consisting of a refrigerator compartment, a vegetable compartment, a chilled compartment, a partial compartment, and a freezer compartment. The refrigerator may have one or more of each of multiple types of cooling compartments selected from the group consisting of a refrigerator compartment, a vegetable compartment, a chilled compartment, a partial compartment, and a freezer compartment.

[0016] Fig. 1 is a schematic perspective view of refrigerator 1. Fig. 2 is a schematic perspective view of refrigerator 1 with the drawers open. Fig. 3 is a schematic plan view of refrigerator 1 with the drawers open. Fig. 4 is a schematic cross-sectional view taken along line IV-IV in Fig. 3.

[0017] As shown in Figures 1 to 4, the refrigerator 1 has a main body 2. The main body 2 has a housing 2a and a cooling mechanism 2b (see Figure 4).

[0018] (Cooling chambers 10a, 10b, 10c, 10d, 10e) As shown in Figures 1, 2, and 4, the housing 2a has multiple cooling chambers 10a, 10b, 10c, 10d, and 10e formed as storage chambers. Each of the multiple cooling chambers 10a, 10b, 10c, 10d, and 10e is open in one direction. Specifically, each of the multiple cooling chambers 10a, 10b, 10c, 10d, and 10e is open to the front. Both widthwise sides and the rear side of each of the multiple cooling chambers 10a, 10b, 10c, 10d, and 10e are covered by the housing 2a.

[0019] In this embodiment, an example will be described in which the refrigerator 1 is provided with multiple cooling compartments 10a, 10b, 10c, 10d, and 10e. However, the present invention is not limited to this configuration. The refrigerator may have, for example, only one cooling compartment.

[0020] As shown in FIG. 4, the housing 2a accommodates a cooling mechanism 2b. The cooling mechanism 2b is a mechanism that generates cold air. The cooling mechanism 2b can be configured, for example, by a refrigerant circuit or a cooling element such as a Peltier element. The cold air generated by the cooling mechanism 2b is supplied to each of the multiple cooling chambers 10a, 10b, 10c, 10d, and 10e, thereby cooling the cooling chambers 10a, 10b, 10c, 10d, and 10e. In this embodiment, the cooling mechanism 2b specifically includes a compressor, an evaporator, a refrigerant path that passes through the compressor and the evaporator, and a refrigerant that flows through the refrigerant path.

[0021] Cooling compartment 10a is a refrigerator compartment that can be cooled to a temperature range higher than 0°C. The set temperature of the refrigerator compartment is, for example, approximately 5°C. The opening of cooling compartment 10a is closed by two doors 12a1 and 12a2 shown in Fig. 1 etc., which can be opened and closed. Doors 12a1 and 12a1 each open and close the opening of cooling compartment 10a by rotating around a rotation axis extending in the height direction at one end in the width direction.

[0022] Cooling compartment 10b shown in Fig. 4 is a vegetable compartment that can be cooled to a temperature range higher than 0°C. The set temperature of the vegetable compartment is, for example, approximately 8°C. Cooling compartment 10b houses drawer 13 that can be pulled out in the front-to-rear direction. Drawer 13 has door 13a that can open and close the opening of cooling compartment 10b by moving in the front-to-rear direction relative to main body 2, and a container that is attached to door 13a.

[0023] Cooling compartment 10c is a small freezer compartment that can be cooled to a temperature range below 0°C, for example. The set temperature of the freezer compartment is, for example, approximately -15°C to -20°C. Cooling compartment 10c is provided in a portion of main body 2 in the width direction (specifically, the right side as viewed from the front). Cooling compartment 10c houses a drawer 14 that can be pulled out in the front-to-rear direction. Drawer 14 has a door 14a that can open and close the opening of cooling compartment 10b by moving in the front-to-rear direction relative to main body 2, and a container attached to door 14a.

[0024] Cooling compartment 10d is an ice-making compartment that can be cooled to a temperature range below 0°C, for example. The cooling compartment 10d has a temperature range of about -15°C to -20°C, for example. Cooling compartment 10d is provided in a portion of the main body 2 in the width direction (specifically, the left portion when facing it). Cooling compartment 10d is located to the left of cooling compartment 10c. Cooling compartment 10c houses a drawer 15 that can be pulled out in the front-to-rear direction. Drawer 15 has a door 15a that can open and close the opening of cooling compartment 10b by moving in the front-to-rear direction relative to the main body 2, and a container attached to door 15a.

[0025] Cooling compartment 10e is a freezer compartment that can be cooled to a temperature range below 0°C, for example. The cooling compartment 10e has a temperature range of about -15°C to -20°C, for example. Cooling compartment 10e is provided across substantially the entire width of main body 2. Cooling compartment 10e houses a drawer 16 that can be pulled out in the front-to-rear direction. Drawer 16 has a door 16a that can open and close the opening of cooling compartment 10b by moving in the front-to-rear direction relative to main body 2, and a container 16b (see Figures 2 to 4) attached to door 16a.

[0026] Drawers 13, 14, and 15 each have a configuration substantially similar to that of drawer 16. Therefore, the following description of drawer 16 also applies to drawers 13, 14, and 15.

[0027] (Drawer 16) Fig. 5 is a schematic perspective view of the drawer 16. Fig. 6 is a schematic exploded perspective view of the drawer 16. Fig. 7 is a schematic exploded perspective view of the drawer 16. Fig. 8 is a schematic perspective view of the drawer 16 as viewed obliquely from below.

[0028] The drawer 16 is stored in a cooling chamber 10e (see Figure 4, etc.), which is a type of storage chamber. The drawer 16 can be pulled out forward from the cooling chamber 10e in the front-to-rear direction. The drawer 16 has a door 16a. When the drawer 16 is stored in the cooling chamber 10e, the door 16a closes the opening of the cooling chamber 10e. The door 16a can be displaced in the front-to-rear direction relative to the main body 2.

[0029] As shown in FIGS. 6 and 7, a metal frame 20 is attached to the door 16a. Specifically, a pair of frames 20a and 20b are attached to the door 16a. The frames 20a and 20b each extend in the front-to-rear direction from the door 16a. The frames 20a and 20b each extend from the door 16a toward the back (rear) side of the cooling chamber 10e. The frames 20a and 20b extend linearly from the door 16a toward the rear. The frame 20a is attached to the right side of the door 16a. The frame 20b is attached to the left side of the door 16a, spaced apart from the frame 20a in the width direction. The method of attaching the frames 20a and 20b to the door 16a is not particularly limited. The frames 20a and 20b may each be attached to the door 16a with fastening members such as screws or bolts.

[0030] As shown in FIG. 6, the container (case) 16b is supported by a frame 20. The container 16b has a recessed portion recessed downward. As shown primarily in FIG. 6, the container 16b has a bottom wall 16b1, a front wall 16b2, a rear wall 16b3, and a pair of side walls 16b4 and 16b5. The front wall 16b2 extends upward from the front side of the bottom wall 16b1. The rear wall 16b3 extends upward from the rear side of the bottom wall 16b1. The rear wall 16b3 and the front wall 16b2 face each other in the front-to-rear direction. The side wall 16b4 extends upward from the right side of the bottom wall 16b1. The side wall 16b5 extends upward from the left side of the bottom wall 16b1. The side walls 16b4 and 16b5 face each other in the width direction. The bottom wall 16b1, the front wall 16b2, the rear wall 16b3, and the pair of side walls 16b4, 16b5 form a recess in the container 16b.

[0031] (Frame 20) The container 16b is inserted from above between the frames 20a and 20b in the width direction. The right end of the container 16b is supported by the frame 20a, and the left end is supported by the frame 20b. Specifically, a pair of side walls 16b4, 16b5 of the container 16b each have a protrusion that protrudes outward in the width direction over substantially the entire front-to-rear direction. These protrusions of the side walls 16b4, 16b5 abut against the upper portions of the frames 20a, 20b. This allows the container 16b to be supported from below by the frames 20a, 20b. The container 16b is suspended by the frames 20a, 20b.

[0032] (Rod-shaped member 30) As shown in FIG. 8, a rod-shaped member 30 is fixed to the frame 20. The rod-shaped member 30 is located at the rear (back side) of the container 16b. More specifically, the rod-shaped member 30 is fixed to each of the frames 20a, 20b at the rear of the container 16b and can abut against the rear wall 16b3 of the container 16b from the rear side. The rear wall 16b3 has a protrusion that protrudes rearward at its upper part. A plurality of protrusions are provided at intervals along the width direction. These protrusions are arranged on the rod-shaped member 30.

[0033] The rod-shaped member 30 has a central portion 30a, a first end portion 30b, and a second end portion 30c. The central portion 30a, the first end portion 30b, and the second end portion 30c are made of an integral metal member. The rod-shaped member 30 can be produced, for example, by bending or pressing a single metal rod.

[0034] The central portion 30a is located behind the container 16b. Specifically, the central portion 30a can abut against the rear wall 16b3 of the container 16b from the rear side, and is disposed below a protrusion provided on the upper part of the rear wall 16b3. The central portion 30a is substantially linear in the width direction.

[0035] The first end 30b is connected to the right end of the central portion 30a. The first end 30b has a portion that extends obliquely upward from the central portion 30a toward the rear. In this embodiment, the entire first end 30b extends obliquely upward toward the rear. Specifically, the first end 30b has multiple inclined portions 30b1, 30b2 that have different inclination angles with respect to the horizontal direction. The inclined portion 30b1 is located closer to the central portion 30a, i.e., closer to the base end, than the inclined portion 30b2, and the inclined portion 30b2 is located closer to the tip end. In this embodiment, the inclined portion 30b1 located closer to the base end has a larger inclination angle with respect to the horizontal than the inclined portion 30b2 located closer to the tip end.

[0036] The second end 30c is connected to the left end of the central portion 30a. The second end 30c has a portion that extends obliquely upward from the central portion 30a toward the rear. In this embodiment, the entire second end 30c extends obliquely upward toward the rear. Specifically, the second end 30c has multiple inclined portions 30c1, 30c2 that have different inclination angles with respect to the horizontal direction. The inclined portion 30c1 is located closer to the central portion 30a, i.e., closer to the base end, than the inclined portion 30c2, and the inclined portion 30c2 is located closer to the tip end. In this embodiment, the inclined portion 30c1 located closer to the base end has a larger inclination angle with respect to the horizontal than the inclined portion 30c2 located closer to the tip end.

[0037] As described above, in this embodiment, an example has been described in which the end portions 30b, 30c have multiple inclined portions with different inclination angles relative to the horizontal, and are substantially entirely inclined relative to the horizontal. However, the present invention is not limited to this configuration. For example, the end portions may include a portion that extends horizontally. For example, substantially the entire end portion may be composed of a single inclined portion with a substantially uniform inclination angle relative to the horizontal. Furthermore, for example, the end portions may be curved such that the inclination angle relative to the horizontal gradually changes toward the rear. In this case, the end portions may be curved, for example, convex upward or convex downward.

[0038] (Fixing manner of rod-shaped member 30) Fig. 9 is a schematic side view showing an enlarged view of the fixing portion between the rod-shaped member and the frame, and Fig. 10 is a schematic cross-sectional view taken along line XX in Fig. 9.

[0039] Next, the manner in which the rod-shaped member 30 is attached to the frame 20 will be described mainly with reference to Figures 9 and 10. Note that the manner in which the first end 30b of the rod-shaped member 30 is attached to the frame 20a is substantially the same as the manner in which the second end 30c is attached to the frame 20b. Below, the manner in which the first end 30b is attached to the frame 20a will be described as an example, and the description will be applied to the manner in which the second end 30c is attached to the frame 20b.

[0040] A fixing portion 31 is provided at the tip of the first end portion 30b. The first end portion 30b is fixed to the frame 20a by this fixing portion 31. The fixing portion 31 extends in a straight line obliquely upward toward the back (rear) side. The angle formed by the extending direction of the fixing portion 31 and the horizontal direction is preferably 10° to 45°, and more preferably 10° to 30°.

[0041] The central portion 30a and most of the end portions 30b, 30c, excluding the fixed portion 31, have a substantially circular cross-sectional shape, whereas the fixed portion 31 has a substantially rectangular cross-sectional shape. In the cross-section, the short side direction of the fixed portion 31 is along the width direction (which is the same as the opposing direction of the first end portion 30b and the frame 20a). In the cross-section, the long side direction of the fixed portion 31 is along the height direction. The fixed portion 31 can be formed, for example, by pressing a portion of the end portions 30b, 30c, which have a substantially circular cross-sectional shape.

[0042] As shown in FIG. 10, the fixing portion 31 is fixed to the frame 20a by a plurality of fixing portions 31a, 31b spaced apart along the longitudinal direction D of the fixing portion 31 (see FIG. 9). Specifically, in this embodiment, the fixing portion 31 and the frame 20a are fixed by the two fixing portions 31a, 31b. However, in the present invention, the number of fixing portions is not particularly limited as long as it is two or more. For example, three or more fixing portions may be provided. The number of fixing portions is preferably two or more and five or less, and more preferably two or more and three or less.

[0043] Next, mainly with reference to FIG. 10, the manner in which the frame 20a and the fixing portion 31 are fixed to each other at the distal fixing portion 31a will be described.

[0044] Of the multiple fixing parts, tip-side fixing part 31a, which is located furthest to the tip (rear side), is fixed to frame 20a by being crimped. Specifically, tip-side fixing part 31a and frame 20a are crimped together with rivets 32 as fastening members.

[0045] More specifically, the distal end fixing portion 31a has a through hole 31a1 that penetrates the distal end fixing portion 31a in the width direction. The frame 20a has a through hole 20a1 formed at a position corresponding to the through hole 31a1 and having an inner diameter substantially the same as that of the through hole 31a1. A rivet 32 ​​is inserted so as to penetrate the through holes 20a1 and 31a1. The rivet 32 ​​has a head 32a, a body 32b, and a flange 32c. The head 32a is located outside the frame 20a in the width direction, and the flange 32c is located outside the rod-shaped member 30. The head 32a and the flange 32c are larger than the through holes 20a1 and 31a1, respectively. The head 32a and the flange 32c are connected by the body 32b. The head portion 32a and the flange portion 32c, which are connected by the body portion 32b, are used to caulk and fasten the frame 20a and the rod-shaped member 30 together.

[0046] A roller 33 is attached to the head 32a.

[0047] A base-end fixing portion 31b is provided forward of the tip-end fixing portion 31a (toward the base end of the end portion 30b). Like the tip-end fixing portion 31a, this base-end fixing portion 31b is also fixed to the frame 20a by being crimped. In this manner, in this embodiment, the multiple fixing portions 31a, 31b of the rod-shaped member 30 are each fixed to the frame 20b by being crimped. However, the present invention is not limited to this configuration. For example, at least one of the multiple fixing portions may be fixed to the frame by a fixing method other than crimping.

[0048] Specifically, the base-end fixing portion 31b is configured as a protruding portion that protrudes toward the frame 20a beyond a portion of the rod-shaped member 30 located around the base-end fixing portion 31b. A through-hole 20a2 is formed in the frame 20a at a position corresponding to the protruding base-end fixing portion 31b. The base-end fixing portion 31b is inserted into this through-hole 20a2 and crimped, thereby fixing the base-end fixing portion 31b to the frame 20b. In this embodiment, the protruding base-end fixing portion 31b is formed by press-molding the rod-shaped member 30. Therefore, a recess 31b1 is formed in the base-end fixing portion 31b on the side opposite to the frame 20a, recessed toward the base-end fixing portion 31b. Note that the protruding portion may be provided in the frame 20a, and the through-hole 20a2 may be provided in the rod-shaped member 30.

[0049] The outer diameter of the distal fixing portion 31a and the outer diameter of the proximal fixing portion 31b are different from each other. The outer diameter of the distal fixing portion 31a is larger than the outer diameter of the proximal fixing portion 31b. Therefore, the distal fixing portion 31a located on the inner side (the distal end side of the fixing portion 31b) is fixed to the frame 20a with a higher fixing strength than the proximal fixing portion 31b is fixed to the frame 20a with a higher fixing strength at the distal end portion than at the proximal end portion.

[0050] (Installation of drawer 16) Next, mainly with reference to FIG. 4, a description will be given of how the drawer 16 is attached to the housing 2a.

[0051] As shown in FIG. 4, the housing 2a is provided with linear protrusions 2a1 located in the cooling chamber 10e. Specifically, protrusions 2a1 are provided on each of two side surfaces of the housing 2a on both sides in the width direction of the cooling chamber 10e. The protrusions 2a1 protrude from the side surfaces of the cooling chamber 10e toward the center in the width direction. The protrusions 2a1 extend approximately horizontally along the depth direction. The frame 20 is inserted into the protrusions 2a1 so as to be displaceable in the front-rear direction. The roller 33 is sandwiched between the protrusions 2a1 lined up vertically and is movable in the front-rear direction.

[0052] The frame 20 and the drawer 16 fixed to the frame 20 slide forward and backward relative to the protrusion 2a1 provided on the housing 2a, thereby allowing the drawer 16 to be taken in and out.

[0053] The case attached to the drawer is supported on both sides of the width by a frame, so the weight of the drawer and the food stored in it is essentially supported by the frame, and therefore, for example, when the drawer is pulled out and stationary, essentially no stress is applied to the rod-shaped member.

[0054] For example, when closing a drawer that is pulled out, the drawer will eventually come into contact with the housing and retract into its stowed state. Therefore, at the end of the closing process, the drawer and the housing collide. Because the rod-shaped member of the drawer restricts the container from moving from the rear side of the rear wall of the container, for example, if the drawer is closed forcefully, due to the law of inertia, there is a risk that rearward stress will be applied to the rod-shaped member when the drawer and the housing collide.

[0055] 9 and 10, the fixing portions 31 of the ends 30b, 30c of the rod-shaped member 30 have portions that extend obliquely upward from the central portion 30a (front side) toward the rear side (rear side), and are fixed to the frame 20 at the inclined portions. Therefore, a horizontally rearward stress F0 applied to the central portion 30a is divided into a diagonally upward stress F1 that is parallel to the extension direction of the ends 30b, 30c of the rod-shaped member 30, and a diagonally downward and rearward stress F2 that is perpendicular to the diagonally upward direction. Therefore, for example, the rearward stress applied to the fixing portions 31 can be reduced compared to when the fixing portions of the rod-shaped member to the frame are provided horizontally.

[0056] Furthermore, the componentized rearward obliquely downward stress F2 is converted into a stress that bends the ends 30b, 30c of the rod-shaped member 30 downward with the fixed portion 31 as a fulcrum. That is, the ends 30b, 30c of the rod-shaped member 30 bend downward and elastically deform, thereby absorbing part of the horizontally rearward stress applied to the central portion 30a. Therefore, the stress applied to the fixed portion 31 is dispersed in multiple directions, and part of the stress can be absorbed by the elastic deformation of the ends 30b, 30c. This makes it possible to prevent the fixed portion 31 from being deformed by a stress applied in one direction to the fixed portion 31.

[0057] Moreover, in this embodiment, the fixing part 31 is fixed to the frame 20 at multiple fixing parts 31a, 31b provided at intervals along the longitudinal direction. Therefore, the fixing part 31 has high durability against stress applied thereto. Therefore, even if a backward stress is applied to the rod-shaped member 30 from the container 16b, the fixing part between the rod-shaped member 30 and the frame 20 is unlikely to be damaged or deformed. This allows the drawer 16 to have high impact resistance.

[0058] From the viewpoint of optimally achieving the effect of improving the impact resistance, it is preferable that the angle formed between the longitudinal direction of the frame 20 (the horizontal direction in this embodiment) and the longitudinal direction of the ends 30b, 30c is 10° or more and less than 45°, and it is more preferable that the angle is 10° or more and 30° or less.

[0059] From the viewpoint of increasing the impact resistance of the drawer 16, it is preferable that the plurality of fixing portions 31a, 31b are fixed more firmly to the frame. Therefore, it is preferable that the plurality of fixing portions 31a, 31b include a plurality of fixing portions that are crimped. It is preferable that all of the plurality of fixing portions 31a, 31b are crimped and fixed to the frame 20.

[0060] Furthermore, the fixing portion 31a located at the rearmost side (tip side) is distant from the central portion 30a of the rod-shaped member 30. Therefore, a strong restoring force acts on the fixing portion 31a when the ends 30b, 30c are elastically deformed. Furthermore, the fixing portion 31a is located away from the fixing location of the frame 20 (the rear surface of the door 16a). Therefore, the amount of displacement of the fixing portion 31a due to torsional deformation of the frame 20 becomes large. Therefore, it is preferable that the tip side fixing portion 31a is fixed to the frame 20 with a fixing strength higher than that of the base side fixing portion 31b. In this embodiment, it is preferable that the outer diameter of the body portion 32b of the rivet 32 ​​is larger than the outer diameter of the fixing portion 31b inserted into the through-hole 20a2 of the frame 20. The outer diameter of the body portion 32b is preferably 1.1 to 2 times the outer diameter of the fixing portion 31b, and more preferably 1.1 to 1.5 times.

[0061] However, it is also possible to avoid using the through holes and the protrusions inserted into the through holes as fixing parts by crimping them. In this case, the number of fixing parts is reduced. This reduces the fixing strength between the frame and the rod-shaped member. For example, if a large weight is applied to the frame and it deforms, the frame with the through holes may slide against the protrusions, causing wear on the protrusions and the through holes, or may generate sliding noise.

[0062] In this embodiment, the base-end fixing portion 31b inserted into the through-hole 20a2 is crimped to form a fixing portion. Therefore, the fixing strength between the frame 20 and the rod-shaped member 30 is high, and the base-end fixing portion 31b is substantially immovable relative to the frame 20. Furthermore, the multiple fixing portions 31a, 31b are provided along a direction inclined with respect to the horizontal direction, which is the extension direction of the frame 20. Therefore, the rigidity of the frame 20 is increased by the rod-shaped member 30. Therefore, deformation of the frame 20 is suppressed. Therefore, in this embodiment, sliding between the frame 20 and the rod-shaped member 30 is suppressed. Furthermore, the load applied to the roller 33 can be reduced.

[0063] (Manufacturing method of drawer 16) 11 is a schematic diagram for explaining the manufacturing process of the drawer 16. Next, the process of joining the frame 20 and the rod-shaped member 30 in the manufacturing process of the drawer 16 will be explained mainly with reference to FIG.

[0064] First, the frames 20a and 20b are attached to the door 16a.

[0065] Next, the rod-shaped member 30 is positioned relative to the frames 20a and 20b. In this embodiment, the fixing portion 31b shown in FIG. 10 is provided with a through-hole 20a2 formed in the frame 20 and a protrusion (proximal-end fixing portion 31b) formed on the rod-shaped member 30 that is inserted into the through-hole 20a2. Therefore, by inserting the proximal-end fixing portion 31b into the through-hole 20a2, the frame 20 and the rod-shaped member 30 can be easily positioned. Furthermore, after positioning, the relative positional relationship between the frame 20 and the rod-shaped member 30 is unlikely to shift.

[0066] Next, the rivet 32 ​​is inserted into the through-hole 20a1 of the frame 20 and the through-hole 31a1 of the rod-shaped member 30, which constitute the fixed portion 31a. At this time, a roller 33 is attached to the head 32a of the rivet 32 ​​in advance.

[0067] Next, the frame 20 and the ends 30b, 30c of the rod-shaped member 30 are crimped together at multiple locations in the same process, thereby forming multiple fixing portions 31a, 31b. This makes it possible to form multiple fixing portions 31a, 31b quickly and easily with fewer processes.

[0068] Specifically, the base-end fixing portion 31b inserted into the through hole 20a2 is pressed by the jigs 41a and 41b from both sides in the thickness direction (width direction) of the frame 20. In the same process, the rivet 32 ​​inserted into the through hole 20a1 of the frame 20 and the through hole 31a1 of the rod-shaped member 30 is pressed by the jigs 42a and 42b from both sides in the thickness direction (width direction) of the frame 20.

[0069] The tip end of each of the jigs 41a and 41b is cone-shaped (specifically, circular cone-shaped) with a protruding center. Therefore, when the base-side fixing part 31b is pressed by the jigs 41a and 41b, at least a portion of the base-side fixing part 31b expands in the radial direction. This causes the base-side fixing part 31b to be crimped and fixed to the frame 20. As shown in FIG. 10, both end surfaces on the tip end and base end of the base-side fixing part 31b become cone-shaped concave surfaces by being pressed.

[0070] In this embodiment, the height of the base-side fixing portion 31b is shorter than the length of the through-hole 20a2. Therefore, pressing does not deform the base-side fixing portion 31b so that the tip of the base-side fixing portion 31b is positioned on the surface of the frame 20 opposite the rod-shaped member 30. Even after pressing, the base-side fixing portion 31b remains substantially positioned within the through-hole 20a2. However, the present invention is not limited to this. For example, before pressing, the height of the base-side fixing portion 31b may be set higher than the length of the through-hole 20a2, and then the base-side fixing portion 31b may be deformed by pressing so that a portion of the base-side fixing portion 31b is positioned on the surface of the frame 20.

[0071] The tip of the jig 42b that presses the tip of the rivet 32 ​​on the rod-shaped member 30 side also has a tapered shape (specifically, a cone shape) with a protruding center. Therefore, when the rivet 32 ​​is pressed by the jigs 42a and 42b, the tip of the rivet 32 ​​on the rod-shaped member 30 side is deformed radially outward. As a result, a part of the tip of the rivet 32 ​​on the rod-shaped member 30 side is positioned on the surface of the rod-shaped member 30. This causes the tip-side fixing portion 31a to be firmly fixed to the frame 20.
